When I enable 'GPU Instancing', transparent object starts flickering.

When I enable 'GPU Instancing', transparent object starts flickering. Some are drawn but shape is changed the others are not drawn.

Here is my custom shader code. just simple unlit, transparent shader and I added some codes for instancing.

 Shader "Custom/Unlit/TransparentUnlit"
 {
     Properties
     {
         _MainTex ("Texture", 2D) = "white" {}
     }
     SubShader
     {
         Tags { "RenderType"="Opaque" "Queue"="Transparent" "IgnoreProjector"="True" }
         LOD 100
 
         ZWrite Off
         Cull Off
         Blend SrcAlpha OneMinusSrcAlpha 
 
         Pass
         {
             CGPROGRAM
             #pragma vertex vert
             #pragma fragment frag
 
             #pragma multi_compile_instancing
 
             #include "UnityCG.cginc"
 
             struct appdata
             {
                 float4 vertex : POSITION;
                 float2 uv : TEXCOORD0;
             };
 
             struct v2f
             {
                 float2 uv : TEXCOORD0;
                 float4 vertex : SV_POSITION;
             };
 
             sampler2D _MainTex;
             float4 _MainTex_ST;
             
             v2f vert (appdata v)
             {
                 v2f o;
                 o.vertex = UnityObjectToClipPos(v.vertex);
                 o.uv = TRANSFORM_TEX(v.uv, _MainTex);
 
                 return o;
             }
 
             UNITY_INSTANCING_CBUFFER_START(Props) 
 
             UNITY_INSTANCING_CBUFFER_END
             
             fixed4 frag (v2f i) : SV_Target
             {
                 // sample the texture
                 fixed4 col = tex2D(_MainTex, i.uv);
                 return col;
             }
             ENDCG
         }
     }
 }

This is when I off 'Enable Instancing' https://drive.google.com/open?id=0B32wWfDTQhRfT0JfdmlKUWw4SHc (link is video) alt text
